To all whom it may concern:

Be it known that I, OsoAR F. DAVISSON, a citizen of the United States, residing at Dayton county of Montgomery", in the State of Qhio, administrator (with will annexed) of the estate of THoMA's CARNEY, late a citizen of the United States, deceased, who did in his lifetime invent certain new and useful Improvements in Cash- Registers, do declare the following to be a full, clear, and exact description of said invention.-

This invention relates to cash registers and has for its main object to provide a so called two department machine to register simultaneously two different classes of transactions. i

The machine is also adapted, and this is a second general object, to use as a cost and selling price machine wherein two registers are provided on one of which the cost prices of goods sold are entered and on the other of which the selling prices of goods sold are also registered. e

Among the objects of the invention may be noted-the provision of improved mechanism for preventing the overthrow of the register and of the indicators by the provision of positive actuating means for the same. An improved zero setting device is provided with means for preventing the tripping of the transfer. pawls when a counter is so reset.

The machine is adapted to use an inserted receipt or slip "and mechanism is provided for feeding this slip slightly-so that additional purchases may be accounted for thereon.

A further improvement consists in the provision of means for printing the amounts of the two departments in distinctive colors.

With'these and incidental objects in view the invention consists of certain novel features of. construction and combination of" parts the essential elements of which are set forth in appended claims and ,a preferred form of embodiment of which is hereinafter described with reference to the drawings vation of the machineqshowing the cabinet in position. Fig. 2 is a tra'nsversevertical sect-ion through the machine on line 22 of- Fig. 1 showing the partsin normal position.

Fig. 3 is a section on line 38 of Fig. 1 showing the parts in adjusted position. Figs. 4, 5 and 6 are detail views of the computing or registering mechanism, Figs. 4 and '5 being transverse sections and Fig. 6 a plan thereof. Fig. 7 is a section on line 7-7 of Fig. 1 showing the main operating device of the machine. Fig. 8 is a section on line 8-8 of Fig. 1 showing the connections to the printing mechanism. Fig. 9 is an elevation of the printing mechanism and the left hand end of the'machine.

As above stated the machine of the present invention is a two department machine and is intendedparticularly to be used as a so called cost andselling price machine. Mechanisms of this type are now in use and are intended to furnish a summation of both the cost and sellin price of articles sold in commercial' establishments. provided and separate banks( of keys controlling each register andit is intended that on one register the'selling prices shall be added and on the other register the cost prices shall he added.

This present machine is a so called two motionmachine in which the keys ac't merely as stops for differential elements, the power to move the elements as well as the indicat- Two registers are ing and printing-devices being furnished by an operating handle or crank lever. In the present machine differential elements are normally locked in zero position and are released by depression of a key which also re leases the main operating element;- The differential elements are positively stopped by the keys and then finally returned and relocked by the operating mechanism. The printing devices are at all times connected to the differential elements so that they are set at each operation remaining set only long- Fig. 1 eight banks of keys are provided each numbered from one to nine inclusive and each. controlling a train of differential elements. It will be understood that all the trains are precisely similar so that a description o one will be sufficient. The

banks of keys 10 are carried in segmental frames and each key is provlded with a pm 12 moving in a bayonet slot 1.3 of a s'egmeir' tal sliding detent 14. When any'key is depressed against the resistance of its returning spring 15 its pin 12 rides down a cam part of the bayonet slot 13 thereby raising the detent 14 when the pins 12 of the remaining keys in the bank pass into the circular portion of the slot 13 and are thereby locked against depression. \Vhen the detent reaches its upper position it is locked therein by one of a series of detent pawls 16 loosely mounted on a shaft 17 and each pro vided with a spring 18 tending to force the pawl to locking position. The upper end. of the detent is provided with a cam slot 19 in which rides an antifriction roller 20 on a bell crank lever loosely mounted on a shaft 27 and comprising arms 21 and 22. It will be understood that one such lever is provided for each bank of keys. Each bell crank lever has mounted thereon a pin 23 moving between spaced projections 24 and 25 of arms 26 rigidly mounted on shaft 27. It will be seen that when any detent 14 is raised the corresponding 'bell crank will be rocked around shaft 27 and through the pin 23 will carry the shaft with it but such movement will not move any of the other bell crank levers inasmuch as projections 24 and 25 are spaced apart .to prevent such movement. On the right hand end of shaft 27 (as shown in Fig. 7) is an arm 28 having.

a pin and slot connection 29 with a locking lever 30 journaled on a pin 31 in the ma-- chine frame. A spring 32 tends normally to rock the lever 30 to a position such that its latching projection 33 is in front of a bell crank lever 34 journaled loosely on the main supporting shaft 35. This bell crank lever 34 is provided in its forward arm with a slot 36 in which rides an antifriction roller 37 mounted on one of the two main operating levers 38. These levers are mounted rigidly on shaft 39 and are returned to normal posit-ion by strong coiled springs 40. It will be clear that projection 33 of pawl 30 normally locks the bell crank lever and thereby prevents movement of the main operating handle as such movement requires the traverse of roller 37 through the cam slot 36. Vvhen however a key is def pressed the shaft 27 is rocked as before stated and this raises latching lever 30 1 enough to carry its projection 33 away from in front of lever 34 and the handle may then be operated. At the end of the operation it is necessary to release the keys and this is provided for by the release of locking ,de-' tents 16. These detents as stated are loose on shaft 17 and rigid with said shaft are frame arms 42 connected by the, rod'43 (see Fig. 2) lying in front of all the'said detents .16. One of the operating levers 38 as shown in Fig. 8 has. a gravity pawl 44 having spaced projections 45 and 46 on opposite sides of a pin 47 carried by the main lever. The rear projection of pawl 44 is adapted to engage and rock the arm 48 rigidly mounted on shaft 17. In Fig. 8 the parts are in normal position and it will be seen that the depression of operating lever 38 will rock pawl 44 around its pivot moving projection 46 up toward the pin 47 and allowing the pawl to pass the arm 48 without moving the same. \Vhen however the handlelever 38 approaches its upper position again the rearward projection of pawl 44 will strike the arm 48 and at this time the projection 45 will lock against pin 47 forcingthe arm 48 rearwardly and thereby rocking the shaft 17 and the rod 43 moved therewith to release the detent pawls 16 when the detents are returned to their normal lower position by springs 51 shown in dotted lines in Fig. 2. It may at times be desired to release the keys without an operation of the machine as for example if a key is depressed by error and with this object a release key 52 is provided (shown'on Fig. 7) pivoted on a pin and having a' downward extension 54 carrying a pin 55. This pin is normally in front of an arm 56 also rigidly mounted on shaft 17 and when release key 52 is depressed it will move the pin 55 rearwardly thereby rocking shaft 17 and releasing the detents 16 as was stated to be the case when the handle approached its normal upward .front of a link 60 connected to the locking bell crank lever 34. The link 60 is also supported by a superjacent link 61 pivoted to the main frame. Vvhen the release key is depressed the arm 58 is rocked in front of the link 60 thereby preventing the operation of the handle levers 38. As soon as the handle starts the link 60 is moved forwardly passing under the arm 58 so that depression of the release key is thereby prevented.

Passing, now to the differential elements reference may" be made to Figs. 2, 3 and 7. The handle levers 38. are connected at their forward ends by a handle bar 71 so that they move together at all times. An antifriction' roller 7 1* carried by each of the leversrides in a curved slot 72 in'operating lever 73 mounted rigidly on shaft .35. It will be seen from the shape of slots 72 that during the first part of the movement oflevers 38 the operating levers 73 will be their 1 lower position. This construction serves to prevent overthrow of the accounting elements. To compel a complete operation of the handle levers 38 one of them. is provided with a double full stroke pawl- 74 of usual construction, a latch 75 serving to retain it in either position as it moves downwardly and upwardly over a rack- 76. This construction is well known in the art. Mounted rigidly on' shaft 35 area series of operating segments 81 one for each bank-of keys. The segments are each provided with a notch 82 for connecting them to the differential elements and with an antifriction roller 83 serving to return-the said elements to normal position Loosely mounted on the shaft 35 are a series of rack segments 84 one for each bank of. keys each provided with a vertically extending arm 85 carrying a main actuating latch 86 and an auxiliary latch 87. The segments 84 are normally locked in zero position by the provision of a series of latches 91 loosely mounted on a rod 92 and pressed by springs 93 between them and a series of collars 94 rigid on said rod so thatthe forwardly projecting ends of the pawls 91 as indicated at 95 are in front of lugs 96 carried by the connecting latches 86. The downwardly extending arms 22 of the bell cranks are each provided with an antifriction roller 96 normally engaging as shown in Fig. 2 with a rearward cam edge of connecting latches 86 thereby holding their for ward projecting ends 97 above the periphery of the segments -81'.- When a key is depressed in any bank its roller 96* is moved away from. the cam edge of the connecting latch 86- when the latch immediately rocks around its pivot 98 under tension of a spring 99 between the latch and a flange 100 of the extension 85 bringing the projection 97 in front of notch 82 of the segment 18 so'that movement of the said segment will produce an equal movement of the connecting latch and its segment 84. The connecting latches are each provided with an upwardly extending part 101 whose path intersects that of the amount keys so that a depressed key and then to rise again through a spring or' its own grayity. This serves to latch the mechanism until the segments 81 return to normal position when the rollers '83- first strike the depending ends 103 of the auxiliary latches 87 rocking the 'flanges 102 below the keys and in their further movement striking the edge of arms 85 and returning them together with the connecting latches and other mechanism carried thereby to normal position. As the connecting latches reach normal position the lugs 96 thereon strike cam edges of the latches 95 depressing them against the resistance of their springs 93 and finally passing to the rear of the said projection when the latches '95 im mediatelyrise and again lock the difi'eren tial elements in normal position. The final increment of return movement of the connecting latches 86 brings their cam edges against the antifriction rollers 96? and again elevates the forward ends 97 above the notches 82 of the operating segments 81. It will be seen that the differential elements.

are locked between operations in zero position, are positively moved to the desired position of differential adjustment, are posi-- tively'held in such position by the depressed keys, and are then quickly returnedla'lso' positively to normal position and there The segments 84 are provided with gear teeth 106 meshing each with-a pinion 107 on a shaft 108 there being as shown in Fig 2 eight of said pinions 107 and a corresponding number of shafts 108. On the other ends of the shafts 108. as shown in Fig. 8 are other pinions 109 gearing with rack segments 110 which are journaled "loosely on shaft 35 and are {each provided with an upwardly extending segment 111 gearing; with pinions 112 on a series of nested sleeves 113. The outer ends of the sleeves 113. are provided with printing wheels 114 as-shown in Fig 9. The segments 84 are also provided bars 121 serving to move the indicators 122 through pinions 123.

' The indicators 122 are held 1n then set.

I Gearing-with segments 116 arev pinions 120 which mesh with vertical rack positions by any suitable alini'ng device' I (not shown) Totalizing, indicating and'printing meclianisln may next be described in the order mentioned. The totalizer 119 comprises a series of wheels having numbers on their periphery and having gear pinions 124' and ratchet pinions .125 as is usual in devices of this type. I T 1e wheelsare'all suppmtedfon a tot-alizer shaft 126 carried by frame arms 127 pivoted on a shaft 128 and one of which frame arms 'as shown in Fig. 3 isprovided with'a rearwardly extending arm 129 carrying at its upper end an a'.ntifriction roller 130'moving in a cam groove 131 of a cam disk 132 on shaft 133. This shaft is given aconiplete rotation at each operation of the machine by mechanism old in the art-and shown in Fig.- 7. Connected to the rear, end

'shown, adapted to gear successively with pinions 136- on shaft 133 and 137 on shaft 117. A flange 138 on the rack bar 135 passes up on the rear side and down on the forward side of the flange 139 being thrown Fig. 4

in opposite directions at the opposite ends of its travel by a spring 140. A gear not shown constantly connects the pinions 136 and 137 the whole mechanism providing for giving a complete rotation to shaft 133 at each operation of the machine. It will be seen from the shape of the cam groove 131 that the totalizer wheels will be slightly depressed into gear with the vertical segments 118 and then raised at the end of the operation, thus providing as is usual for movement in one direction only of the counter wheels. The supporting shaft 128 for the totalizer supporting frame is a transfer shaft for the machine. As shown 1n Flgs. 2 and 4 th1s shaft is provided wlth a series of helically arranged cams 141 for operating the transfers successively. Trip plungers 142' are provided one for each totalizer wheel normally pressed rearward by coiled springs 143. Beside each totalizer wheel is a disk 144 having two projections 145 and 146 and also having pivoted thereto at 147 a transfer pawl 148 which is normally drawn by a spring 149 into contact with the ratchet teeth 125. The disk 144 has a cut away portion 150 in which the plunger 142 normally extends thereby preventing movement of the disk and the transfer pawl. Each wheel except the one of highest order has a trip cam 151 moving therewith which when the wheel passes from nine to zero strikes the rearward end of the trip plunger 142 for the next higher order and moves the sameforwardly enough to carry the end of said plunger away from the cut away portion 150 of the disk 144. The disk then immediately swings in clockwise direction (see Fig. 5.) around its pivot on shaft 126 until projection 145 strikes the trip plunger thereby bringing the other projection 146 into the path of one of the helical cams 141. The swinging of the disk. 144, as above explained, is caused by the spring 149 (see At each operation of the machine a complete rotation is given to the transfer shaft 128 by the train of gearing shown on Fig. 8. ()ii shaft 133 is a mutilated gear 161 servingto give a half. rotation to the gear 162- 'which meshes with a pinion 163 of half its This mechanism evidently serves to lock the gear 162 while gear 161 makes'half its rotation and to allow move ment of gear 162 during the other half ro tation of shaft 133 and gear 161 resulting therefore in a complete rotation of shaft 128 to turn in the transfers. This returns the disk 144 to such position that the notch 150 is again engaged by the plunger 142. To reset the totalizer elements the shaft 126 is provided with a notch and each wheel has a pawl adapted to pass into the said notch when the shaft is rotated through a pinion 166 (see Fig. on the end thereof gearing with a beveled pinion 167 operated from a key 168. hen the kgy is turned the register shaft 126 is given a complete rotation picking up the numeral wheels and carrying them forward until the zero position is reached. At this operation it is necessary to prevent the tripping of the transfer pawls as otherwise m-is-operation of the machine would result and to this end fastened to the shaft 126 adjacent to each-numeral wheel is a cam "flange 171 adapted to engage a pin .172 projecting from a detent pawl 173 loosely mounted on shaft 128. The disk 144 carrying'the transfer pawls is provided with a transverse lug 174 and when the flange 171 reachesnearly the home position it abuts and lowers the detent pin 172 carrying the pawl 173 into the path of lug 174 thereby preventing the retractive movement of the transfer pawls. When the register wheels reach complete zero position the cams 171 fast to the shaft 126 pass beyond pins 172 and the, detents 173 may immediately move to their usual holding position. a

It has been stated that 011 the outer ends of the nested sleeves 113 are the printing wheels 114 there being eight wheels in the present machine. The machine is adapted to print on a detail strip and on an inserted slip and means are provided for feeding both the strip and slip at each operation. The detail strip 200 is stored on a roller 201 passing under and around supporting pins 202 and being wound on a roller 203. To provide a feed of the detail strip the roller 203 is rigidly fastened to pinion 204 connected, through gear 205 with an operating gear 206. It will be remembered that the ban:

213 for feeding the inking ribbon 214 which passes over a roller 215 driven with said.

gear. The ribbon is also supported by a be seen that the inking ribbon 214 passes completely around the printing wheels so that an impression may be takeh both at the top and at the bottom thereof, it being understood thatthe printing wheels as usual in this art are provided with two sets of type from zero to nine inclusive.

.The inserted slip is placed ona table at the side of the mechanism shownin Fig. 1 and, thereby brought. under the printing wheels 114. It mayibe desired at times to print a number of. amounts o t-he sales-slip andfor this urpose mechanism is provided for slightly feeding the slip after each operation. (lonnectedto the gear'212 is a large friction feeding roller221 and an'additional roller 222 is-adapted to be-raised into contact with the same during partof each operation. This roller 222 is mounted in a frame on a a pin 223 and between this frame and an arm 224 is a compression spring 225. The and 224 at its lower end has-an anti friction roller 226 adapted to be moved forwardly when the shaft 39 is rockedby cam edge 228 p 229 is loosely mounted on the shaft 39 beside-the arm 207 and has a cut away po'rtion230 in which moves 'the pin 231'on said arm 207. The arm 229 is also cut away to'pass around the friction roller 226 and as arm 207 moves downwardly with the handle lever the cam edge 228 thereof will gradually force roller 226 forwardly thereby moving the friction roller 222 up against the roller 221. When the roller 226 is thusforced'forwardly it passes out of its appropriate cut away portion of arm 229 and said arm is then. free.to drop down to maintain said roller in forward position. The provision of the arm 229 is merely to maintain the two friction feeding rollers in contact somewhat longer than T would be the case if only arm 207 was provided as it,would be .impossible to provide a cam edge of arm 207 sharp enough to force a roller 226 rearward at the proper time. The roller 226 needs to be maintained in itsforward positionwduring practically the whole upward stroke of arm 207 .but should not be moved forward until nearly the complete downward-stroke of arm 20'? has taken place inasmuch at this timethe slip is being printed andif rollers 221 and 222 were brought together a feed of the slip would result possibly causing a blurred impression to be taken; i

To cause an impression on the slip and strip two platen arms 2'40 and 241 are provided pivoted at 242 and 243 and drawn to striking position by'springs 244 and 245. The platens are connected by a pin and slot 246 and are moved away from the printing type to tenr on the driving springs through an ar1n24'1 connected ti theslip printin platen. This arm bears at its rearward end an anti, friction roller 248 under which is a vertical arm 249 having a cut away portion and fastened to a rearward extension of arm 207. A' spring 250 between the arm 249 and the arm 207 serves to throw the upper end of arm 249 forwardly. When the handle levers are depressed .the shaft 39 is rocked and arm 249 carried upwardly thereby withdrawing th'plate'n arms from the pr nting type and tensioning the driving springs, and-this movement continues until an adjustable piece 251 on arm 249 strikes a stationary pin 252 when the arm 249' is rocked rearwardly (enough to release the same from roller 248 the springs 244 and 245 immediately thereafter driving the platens against the strip and the slip. As the bandle levers return to normal position both the strip and slip are fed by the mechanism previously descrlbed.

Thee indicator rack bars 121 are provided arms 278 which are suspended from a rod 279. At one end of this rod 279 and also rigid therewith is an arm- 280 bifurcated-at its forward end tosurrcmnd a cam on shaft 133 the arm'280 being provided with anti friction rollers28l and 282 directly abutting the cam. Rigidly mounted on shaft 35 is an ing arms 286 and a'connecting rod 287. The

and it will be seen from this figure and from Fig. 3 showing the parts inoperated position that the arm 280 is rocked downwardly thereby throwing the arms 278 rearwardly and moving the rack bars 121 away from their driving pinions .120. As the handle the frame bar 287 raised to the position of Fig. .3. If any of the indicators have been set at the previous operation this will r eturn them-to the position such that zero appears.- During the latter half-of the operation the arm 280 is reversely moved throwing the rack bars 121 forward into the. position of Fig. 2 and therefore during the return of the differential elements including the segments 84 vthe rack bars 121 will be moved down wardly the proper distance to set the indicators at the desired amount. The arms 27 8 extend slightly above the shaft 279 and are provided with loosely mounted ers 291 on the indicator bars 121. This mechanism is for the purpose of retaining in If this mechanism was not present,, .when the arms 27 8 are rocked rearwardly removing the rack bars 121 from mesh with pinparts are shown-in Fig. 2 in normal position,

normal position any of the indicators which have not been set at the previous operation.

ions 120 the bars would immediately drop;

at the top for fitting around the roller 248 at their lower ends with long slots 27 6 ridk ing on anti'friction rollers 277 supported an arm 284 (Figs. 2 and 3) and connected with I this through a link 285 is a frame comprlsbars 38 descend the shaft 35. is rocked and i latching pawls 290 adapted to engage roll- I unnecessary movement.

It will be seen that the timingof the indicator throwing devices is such that the rack bars 121 remain in gear at the end of the operation. so that overthrow of the indi- 'cating mechanism is positively and absolutely preventec. This is a very important object to be attained in machines of this yp It will be seen that on Fig. 1 indicators are provided for one series of banks of keys only and this would-be the case in practice when the machine was to be used as a cost and selling price machine as of course it would not be desired to exhibit the cost price of articles sold. If the machine is used as an ordinary two' department register then an additional set of indicators would be provided. The two sets of printing wheels are arranged to print in two different colors such for example as red and black by the use of two inking ribbons of the said colors.
